Metro Vancouver Implements the Most Sophisticated Odour Monitoring Network in the World!

Scentroid has been awarded a contract to install a network of Scentinal Compact Air Quality Stations, Gas Chromatograph Analyzers, and live dispersion modeling software to provide real-time odour monitoring. The system employs Chromatotec’s Medor line of sulfur compound isothermal GC analyzers capable of detecting H2S, DMS, MM, and 12 other compounds to sub ppb accuracy.

The data is then fed to Scentroid’s odour prediction algorithm which uses deep learning technology to map the sensor data to numerous SM100i field olfactometery readings to determine the odour concentration in OU/m3. Additional Scentinal SL50s are placed for direct emission measurements of high odorous sources such as aeration tanks, Inlet works, and sludge dewatering. The SL50s have the same built-in deep learning algorithm that will calculate the odour concentration of the gases being emitted.

All data is sent to Scentroid’s Total Odour Management System (TOM) which utilizes fuzzy logic algorithms to continuously update a live air dispersion model. Metro Vancouver can now not only detect changes to process emissions instantaneously but also verify complaints, predict odour episodes and even optimize process variables to achieve minimal odour impact.
